Kinsey (2004)

This movie builds on the life of Alfred Kinsey (1894 – 1956), a biologist and sex researcher, also known as the father of the modern sexual revolution. He studies the sexual behaviour of American people in 1948 and 1953 and releases reports.
His researches include sex histories of over 18.000 people.
Alfred became famous because at this time sex talk was a taboo, so people had a little knowledge about sex. The little knowledge made people feeling guilty and worried.
He gave sex advice to many people.
